Ziehm Imaging
German mobile C-arm specialist. Primary non-OEC competitor in the global mobile C-arm market. Focus is premium mobile fluoroscopy for surgical, vascular, cardiac, orthopedic, and pain-management use, with intraoperative 3D capability via cone-beam CT extension. Smaller product portfolio than the Big Three but deep single-modality specialization. Privately held.
Company history
- 1972 — founded in Nuremberg.
- 1990s–2000s — establishes U.S. and European presence through direct sales and distributor networks.
- 2006 — Vision family launches with flat-panel detector options, an early flat-panel mobile C-arm at a time when GE OEC's installed base was still predominantly image-intensifier.
- 2010s — Vision RFD (Retractable Flat Detector) and Vision RFD 3D (intraoperative CBCT) expand the premium product line.
- 2017 — acquired by ATON GmbH (private investment); commercial trajectory continues independently.
- 2020s — Naviport navigation integration, Solo / Compact platform refresh, continued flat-panel product evolution.
Product line
- Vision RFD family — premium full-size C-arms with flat-panel detectors. Primary rivals to the OEC 9800 family and 9900 Elite.
- Vision RFD 3D — intraoperative cone-beam CT capability for spine, ENT, and orthopedic trauma.
- Ziehm Solo / Solo FD — compact mobile C-arm for pain management, interventional, and small-OR use.
- Ziehm 8000 — legacy image-intensifier family with substantial installed base in older ORs.
Distinctive technology
- Retractable Flat Detector (RFD) — the detector folds down for transport, then deploys for imaging. Practical advantage for moving C-arms between ORs through standard doorways.
- SmartScan CBCT — intraoperative 3D reconstruction from a single sweep on Vision RFD 3D.
- SmartVascular / SmartCardiac / SmartOrtho — application-tuned image-processing packages.
- Naviport integration with surgical navigation systems — competing posture against the Medtronic O-arm + StealthStation integrated workflow on the imaging-only side.
- Liquid cooling on premium tubes for sustained-fluoro vascular and cardiac procedures.
Market position
Clear #2 globally in full-size mobile C-arm, behind GE OEC. Stronger share in Europe than in the U.S., with notable installed base in surgical-suite-heavy hospital systems. Flat-panel detector adoption was earlier than OEC at comparable tiers, which shaped European hospital procurement patterns through the 2010s. Direct competitors:
- GE OEC (9800 / 9900 Elite) — global market leader.
- Siemens Cios Alpha — flat-panel premium competitor.
- Philips Zenition — flat-panel mid-premium competitor.
Refurb posture
- Vision RFD / RFD 3D refurbs are growing as the flat-panel installed base ages — service-network reach is strong in Europe and adequate in the U.S.
- Vision RFD 3D licensing is the price-determining variable on premium refurbs — confirm CBCT, SmartScan, and application packages.
- Ziehm 8000 image-intensifier units remain in service in many older ORs; refurb pricing is value-tier and parts are mature.
